多跳远程量子态制备
Controlled Bidirectional Remote Quantum Control
摘要
Abstract
Multi-hop remote quantum state preparation has significant value in wireless quantum communication networks and long-distance delivery of quantum information. Fusing the ideas of multi-hop teleportation and remote state preparation, this paper puts forward a novel protocol for implementing multi-hop remote arbitrary single-qubit state preparation. In each hop, it employs the three-qubit non-maximally entangled GHz-type state as the quantum channel. The original single quantum state is prepared hop by hop via intermediate nodes through remote state preparation, and the recovered qubits are used as the prepared state for the next-hop remote state preparation. By analyzing one-hop and two-hop, it obtains the successful probability of remote state preparation after n-hop remote state preparation. Only Pauli operations, single-qubit measurements and the feed-forward strategy are used in this protocol, so this scheme is easily realized in physical experiment.关键词
